Liebert NXC

Liebert NX 10 – 30kVA

Liebert NX is a mid-sized, three-phase uninterruptible power supply (UPS) system that delivers complete, centralized data center power protection. Designed to meet the high availability power needs of a wide variety of IT applications and equipment, the UPS combines compact size, advanced operating features and low cost of ownership.

Product Description

The 120/208-Volt, three-phase version of the Liebert NX is available in four sizes including 10kVA, 15kVA, 20kVA and 30kVA capacities.


  • On-line UPS with dual bus compatibility
  • Allows paralleling for capacity or redundancy
  • Offers highest output power quality, with low THD
  • Operates with high energy efficiency



  • Power communications available through a Relay Contact Card, OpenCommsâ„¢ Web Card and MultiLinkâ„¢ shutdown software.
  • Ultra-quiet performance with noise levels below 54dB allows greater latitude in where to place the unit.
  • Large and user-friendly LCD display provides operating information in twelve languages.
  • Up to three Liebert NX modules can be paralleled and a fourth added for redundancy without using a centralized controller or centralized static switch.
  • For safe and convenient servicing of the UPS, the unit includes a built-in maintenance bypass. Optional wrap-around maintenance bypass is also available.
  • Easy servicing due to front accessibility of critical components, self-diagnostics and various monitoring options.

Higher Availability

  • True on-line double conversion technology corrects all types of power fluctuations.
  • Advanced inverter control technology provides the highest output power quality.
  • Redundant power supply cords, redundant cooling fans and highly efficient cooling of critical components.
  • Minimized transfer to battery, reducing the number of charging and discharging cycles, due to the wider input voltage window of +10 to -20% and a frequency tolerance of 40Hz to 72Hz.
  • Compatibility with dual bus synchronization system enables you to transfer the load to an alternate power source for maintenance activities.
  • High overload protection handles 125% for 10 minutes, 150% for one minute and a 1000% overload for 10 milliseconds.
  • An intelligent battery management algorithm monitors the battery to detect any premature battery failure.

Lowest Total Cost Of Ownership

  • Temperature-compensated battery charging extends battery life.
  • Highest possible input power factor for maximum efficiency.
  • Adjustable power walk-in from 5 seconds to 30 seconds, along with reduced input current distortion and power factor correction, also enables you to save money by reducing back-up generator sizing requirements.
  • The unit’s compact footprint requires less floor space, leaving you with more room for other equipment.

Ideally Suited For

  • Server rooms and mid-sized data centers
  • Network components including critical routers and switches
  • Networks (LAN and WAN)
  • Industrial process and motion automation for mid-sized plants
  • Medical diagnostic/imaging equipment
